Description

technical field

[0001] Coatings, adhesives and polymer additives. technical background

[0002] There are many ways to protect base metals (such as ships, bridges, aircraft and building components) from corrosion. Among them, coating anti-corrosion is widely used because of its simple construction, economical applicability, freedom from equipment area and shape, and certain decorative effects. Applications. At present, most of the coatings used in industry are solvent-based coatings, especially epoxy primers, most of which use xylene and n-butanol as solvents. These solvents have varying degrees of toxicity. When they volatilize, they not only cause environmental pollution, but also seriously endanger construction. the health of personnel. With the enhancement of people's awareness of environmental protection, new anti-corrosion coatings that do not contain organic solvents or low volatile organic compounds (low VOC) have been developed one after ...
